Procedure

A mixture of 500 mg of methyl 4-mercaptobenzoate, 1.6 g of potassium carbonate, 1.2 g of 2-bromoethylmethylether and 329 mg of tetrabutylammonium iodide in 10 mL of acetone was refluxed for 16 h. The reaction mixture was diluted with ethyl acetate, washed with H2O and concentrated. Purified by silica gel chromatography (0-50% ethyl acetate/hexane) to yield 4-(2-methoxyethylthio)benzoate. 240 mg of 4-(2-methoxyethylthio)benzoate was reacted via Procedure R to give 4-(2-methoxyethylsulfonyl)benzoate. 120 mg of 4-(2-methoxyethylsulfonyl)benzoate was hydrolyzed via Procedure M to yield 4-(2-methoxyethylsulfonyl)benzoic acid. 50 mg of 4-chloro-3-(pyridin-2-yl)aniline was coupled to 4-(2-methoxyethylsulfonyl)benzoic acid via Procedure G. The product was purified on reverse phase HPLC to yield N-(4-chloro-3-(pyridin-2-yl)phenyl)-4-(2-methoxyethylsulfonyl)benzamide. MS (Q1) 431.0 (M)+.
